Flying at the field

Question for the day: How many of the "founding fathers" of MMAA does it take to start a Kadet Senior? Count 'em. Mike, Ed, and John. A truly exceptional trio. By the way the airplane survived this devious bunch. I plead innocent in all indignities this poor airplane suffered. [br][br]

Here's what I'm working on. It's called the 'Ona'. It's all scratch built from plans, they were in Spanish so it was done without any instructions. The wing will be somewhat hard to cover because it is under-cambered. I goth the plans here: HPA - Builders' Plan Gallery [br][br][br][br][br][br][br][br][br][br][br][br]

Is the Rheinland the 125 inch one I was able to find on the web? BTW, a note about the CG calculators on this website: the first one is a link to a NASA site that apparently has changed content wise since this link was placed here. It won't be of use. However, the second one will do the trick. It is more complex than you probably need, but will do the job. A constant chord wing should make it very simple to apply. I think if you do a bit of snooping on the web, you'll find that for a trainer with a constant chord wing a good starting point is 25% of the MAC. At 30% it should still be fairly stable, but more sensitive than at 25%. There are always exceptions but I'd never assume there was no mistake in the manual. In any case, the calculator that takes tail moment, and horizontal tail area into account may be the best bet. For ALL you ever want to know about calculating your CG visit http://www.theampeer.org/cg/cg.html You may need a drink afterward.
